School project

Hi. I am after some help/advice on a project that my daughter wants to do for school. The concept is a recordable device that would allow users to read a message or story and/or play music onto a SD card that could then be placed into another device and listened to by a child if they were away from home for a long period of time (in hospital etc.). I said I would help her make something not realising the extent of the project ???.I have a little understanding of how it should work but cannot seem to get it set up correctly. I have on hand a duinotech Leonardo r3 board (XC-4430), a data log module of the same make (XC-4536), a mp3 recording module (XC-4516) and an amplifier (XC-4448), along with a speaker. As well as these components I have on hand various wires etc. My question is whether or not it is possible to join all these components together in order to make a device capable of the above? What sort of coding would be needed in order for the device to function?

Many thanks in advance for any help/advice.

So, a tape recorder? There are many representive projects in a Google search: "arduino mp3 sd recorder player"

These kinds of projects tend to be a bit involved with glue-code to hook together libraries for the physical components. It is certainly not beyond an experienced Arduino high school student, but seems overly difficult for a beginner. To further complicate things you are describing 2 physical units: one to record and one to play which are both nearly identical. (You could cheat and have the recorder write mp3 only to an SD card which can be typically played on most notebooks with a USB adapter.)

The above being said, if you can find a complete project then you may be able to assist her enough to pull this off but I'm not sure what she will take-away.

Crispie: I said I would help her make something not realising the extent of the project

Perhaps a reexamination of what the extent of the project really is would be in order. You could probably do what you describe, but you sound dangerously close to re-inventing the wheel, while the kid in the desk in front of your daughter does it all with her phone.

Take a look at what was done here to record to SD card and playback. http://forum.arduino.cc/index.php?topic=180769.0

Sorry but I had to spread it to get the basics of your post.

Buy a voice recorder w/ SD card capability. Remove its bits from the casing. Duct tape it to a piece of cardboard. Be an hero.

OMG! I spewed my coffee :o

Crispie, however may miss the humorous undertones of your comment. Sufficd it to say, Crispie, that we have all taken a bite from the apple of knowledge only to find that the scope/effort involved is daunting. Worst for you, you are a parent trying to help your child.

TomGeorge has done a bit of organizing. I attempted to refine a search with all of your requirements but it broke Google ... the best I could do was https://forum.arduino.cc/index.php?topic=351210.0

One of my friends did build out an mp3 player for his young daughter which could be a prototype for the player.

Thanks for the feedback. Had already considered the duct tape option. I guess the KISS mantra applies. I will have a look at the links and see what I can come up with. Thanks Tom for cleaning up my messy post.

No offence.

Ow reinventing the wheel project :D I have few options

Sony ICD-LX30 15$~30$ |500x335

Sound Recording Voice Module WTR010-SD 10$

I can post more but would be more like a spam, the last one is a good idea and cheap. Anyway with arduino you will need a sound module so 10$ is not expensive to do all the job, and you don't really need arduino boards.

Or you can use arduino and use the bellow module as Input/output audio.

ISD1820 2$ |500x500
